NewsWine’s leftovers could help wean chicken farms off antibiotics
Every year, millions of gallons of wine are pressed, leaving behind a mountain of pulpy residue that wineries struggle to dispose of. Now, researchers say this overlooked byproduct could serve as a replacement for the antibiotics routinely added to chicken feed.

NewsScientists highlight the cost of delaying childhood vaccination
Delaying hepatitis B vaccination after birth increases infections among newborns and decreases their survival rates and quality of life. A new study found that the longer the delay, the higher the cost in human life and health care.

NewsTrace levels of food pathogen do not always translate to health risk, says study
Ultra-sensitive food safety tests may drive food waste and unavailability with limited public health benefit, according to a study. These food safety measures and ultra-sensitive tests may drive edible food being thrown away, excessive packaging, and extra costs for consumers.

NewsFungi could transform leftovers into lifelines
A new paper outlines an ’emerging circular fungal biorefinery’ – a system in which low-value agricultural byproducts are converted through fungal fermentation into high-protein, nutrient-rich foods.

NewsMicrobes harvest metals from meteorites aboard space station
Microorganisms can harvest crucial minerals from rocks and could provide a sustainable alternative to transporting much-needed resources from Earth. Researchers have studied how those microorganisms extract platinum group elements from a meteorite in microgravity, with an experiment conducted aboard the International Space Station.

NewsManagement practices can enhance soil microbiome functions in plant defense
Researchers analyzed surveys and soil samples from 85 organic farmers in New York to investigate the interaction between beliefs, management practices, and soil microbiome functions.

NewsPathogen risk: Removing southern African fences may help wildlife, boost economy
Fences intended to protect cattle from catching diseases from wildlife and other livestock in southern Africa are in disrepair, restrict wild animal migrations and likely intensify human-elephant conflict – but a plan to remove key sections could make both livestock and wildlife safer.

NewsGolden Gate method enables rapid, fully-synthetic engineering of therapeutically relevant bacteriophages
Researchers have described the first fully synthetic bacteriophage engineering system for Pseudomonas aeruginosa. In this method, researchers engineer bacteriophages synthetically using sequence data rather than bacteriophage isolates.

NewsDose of psilocybin, dash of rabies point to treatment for depression
Researchers used a combination of psilocybin and the rabies virus to map how – and where – the psychedelic compound rewires the connections in the brain. Specifically, they showed psilocybin weakens the cortico-cortical feedback loops that can lock people into negative thinking.

NewsDeadly pathogens found in commercial raw cat foods
An analysis of commercial raw cat foods detected disease-causing microbes, including some that are resistant to antibiotics, creating risks for both pets and their owners, according to a new study.

NewsResearchers create improved natural blue food dye from algae
Food scientists have created a natural blue food dye made of algae protein that could replace petroleum-based artificial food colorants with a stable, adaptable option.

NewsResearchers explore ways to better safeguard romaine supply from E coli outbreaks
E. coli outbreaks in romaine lettuce have long been a public health concern. and now a new paper suggests that a combination of efforts in the field, and even postharvest techniques, can minimize risk to human health.

NewsHarmful algae blooms have secret to success over other algaes
An alga that threatens freshwater ecosystems and is toxic to vertebrates has a sneaky way of ensuring its success: It suppresses the growth of algal competitors by releasing chemicals that deprive them of a vital vitamin.

NewsAvian flu has major economic costs for dairy industry
A new paper shows that the highly pathogenic avian influenza H5N1 virus causes severe mastitis and decreased milk production in dairy cows, a drop-off that may extend beyond the clinical outbreak period.

NewsBacteria hitch a ride on yeast puddles to zoom around
Researchers found that bacteria can speed up by using the fluid pockets shaped by neighboring yeast cells. These microscopic moisture trails allow bacteria to swim farther and spread faster—revealing a new way for microbes to travel through soil, plants, and the human body.

NewsCotton virus circulated undetected in US fields for nearly 20 years, study finds
A virus responsible for damaging cotton crops has been lurking in U.S. fields for nearly 20 years – undetected. Cotton leafroll dwarf virus (CLRDV), thought to be a recent arrival, was infecting plants in cotton-growing states as early as 2006.

NewsTopical gel relieved ear infections in animals after just one dose
Researchers report a topical antibiotic gel that, applied once, cured middle ear infection within 24 hours in chinchillas. a single dose of treatment for middle ear infections could improve patient compliance and potentially reduce pediatric antibiotic usage.

NewsNew AI technique can uncover antiviral compounds using limited data
Artificial intelligence algorithms have been combined with traditional laboratory methods to uncover promising drug leads against human enterovirus 71 (EV71), the pathogen behind most cases of hand, foot and mouth disease.

NewsBacterial ‘jumping genes’ can target and control chromosome ends
Researchers have discovered a new mechanism that transposons, or “jumping genes” use to survive and propagate in bacteria with linear DNA, with applications in biotechnology and drug development.

NewsNew COVID-flu vaccine platform could provide broad, lasting protection
Researchers have developed a new vaccine platform that could provide more robust, longer-lasting protection from both COVID-19 and influenza, and broader immunity to different flu strains.
